A contract is less useful if the stronger party can ignore it whenever convenient. Courts provide an institutional route for asking what happened, which rules apply, and what consequences should follow. They make some disputes answerable through a recognized procedure rather than only through bargaining strength or private retaliation.

The US federal court structure illustrates distinct trial and appellate roles: establishing facts and applying law, then reviewing specified aspects of the decision. Other legal systems divide these functions differently. A court's jurisdiction defines which matters it is authorized to hear.

A judgment needs a system

Imagine a small supplier claiming that a larger customer has not paid. A credible court can change the negotiation before a case is filed because both sides know a third party may enforce the relevant obligation. That possibility depends on more than an impressive courthouse.

People need access to the process, understandable procedures, and an opportunity to present their case. Delay and legal costs can make a formal right difficult to exercise. Judges also need sufficient independence to decide against powerful actors, while their own authority needs public justification and review.

Finally, a judgment must be carried out. Courts depend on wider institutions for enforcement. The social technology is therefore an arrangement of rules, professional roles, records, and coercive authority—not simply a wise person settling arguments.
